Filed: 1989-08-09
Abstract: Mit Hilfe des Inkrementers kann eine Eingangsbinärzahl 
um eine Einheit verändert werden. Dazu besteht der Inkre­
menter aus einem ersten Schaltkreis CL, der aus den 
Bitstellen (d) der Eingangsbinärzahl Schaltsignale (p) 
erzeugt, die für die niederwertigste Stelle (d0) 
gleich dem Wert dieser Stelle ist, bei höherwertigeren 
Stellen durch UND-Verknüpfung der niederwertigeren Bit­
stellen der Eingangsbinärzahl erzeugt wird. Mit Hilfe 
einer Ausgangsstufe, der die Eingangsbinärzahl (D) und 
die Schaltsignale (P) zugeführt werden, werden die Bit­
stellen der Ausgangsbinärzahl (A) erzeugt. Dabei wird 
die niederwertigste Bitstelle der Ausgangsbinärzahl 
durch Invertierung der niederwertigsten Bitstelle der 
Eingangsbinärzahl gewonnen. Die höherwertigeren Bitstel­
len der Ausgangsbinärzahl werden aus den zugeordneten 
Binärstellen der Eingangsbinärzahl gewonnen, wobei eine 
beliebige, eine i-te, Bitstelle der Ausgangsbinärzahl 
gleich der i-ten Bitstelle der Eingangsbinärzahl ist, 
wenn das Schaltsignal des ersten Schaltkreises (CL), das 
aus den Bitstellen 0...i = 1 gewonnen worden ist, binär 
1 ist. Sonst wird diese Bitstelle (d (i)) der Eingangsbinär­
zahl in invertierter Form zum Ausgang durchgeschaltet. 
Der erste Schaltkreis kann so aufgebaut werden, daß 
zur Erzeugung der Schaltsignale jeweils Teilschaltungen 
vorgesehen werden, die eine gleiche Anzahl von Stufen 
aufweisen. Es entsteht somit eine regelmäßige Struktur, 
die leicht erweiterbar ist. Die Ausgangsstufe muß ledig­
lich Multiplexer vorsehen, die in Abhängigkeit der Schalt­
signale entweder die Bitstellen der Eingangsmehrzahl direkt 
oder invertiert durchschalten.

Title: Peripheral device power activation circuit and method therefor
IPC: G05F1/10
Filed: 1989-11-30
Abstract: A first embodiment of the present invention has 
toroidal current transformer 11 having its outputs connected 
across full-wave bridge rectifier 12. The induced, rectified 
current produced by full-wave rectifier 12 is converted to a 
voltage by a load resistor. This voltage is compared to a 
reference signal, the magnitude of which corresponds to a 
quiescent current level, by comparator 13. When the load 
resistor voltage exceeds that of the reference voltage, a 
current surge is detected. The output of comparator 13 is 
directed to a retriggerable monostable multivibrator 14 which 
produces an activation pulse of a selectable and known 
duration. The activation pulse is directed to an 
electromagnetic or solid-state relay 16 which activates 
peripheral device 2 by connecting it to its power supply.  
     The second embodiment of the present invention has line 
sensor 18 electromagnetically coupled to power supply line 3 
the output of current sensor 18 is integrated by integrator 
19. The integrated signal is then digitized by digitizer 20 
and input into selector 21. A crossover detector 28 and line 
voltage sensor 25 are operably connected to power supply line 
3 to monitor the crossover points and voltage level of the 
supply. The monitored voltage is digitized by digitizer 27 
and input into selector 21. Selector 21 alternatively 
supplies microcontroller 22 with the digitized line current 
and voltage level values. Microcontroller 22 compares the 
relative values of the line current and voltage level to 
detect current surges in power supply line 3 due to increased 
activity of parent device 1. Microcontroller 22 then 
activates solid-state relay 24, thereby activating peripheral 
device 2.

Title: Method for determining the characteristics of diffusion sources interacting with a wave, particularly in lidar systems for investigation on the atmosphere and related device
IPC: G01S17/95
Filed: 1989-12-22
Abstract: The probability distribution of the dimensions of 
scattering sources is calculated by the measurement (5 
to 7) of their coefficient of attenuation for several 
wavelengths. In the case of sources having the same 
dimensions, the probability distribution of any other 
stochastic variable connected with the scattering 
process can be calculated.  
     The preferred application is in lidar techniques for 
the remote measurement of the distribution of the 
dimensions of aerosols in the atmosphere, and in 
particular of water droplets in clouds, by the analysis 
of the intensity of the back scattering.

Title: Method for determining degradable organic matter in water
IPC: G01N33/18
Filed: 1990-01-23
Abstract: 1. Method for continuously and quantitatively determining organic and inorganic carbon compounds (C compounds) in water. 2.1 Hitherto inorganically bound carbon was converted by acidification into carbon dioxide (CO2) which was expelled from the water with a gas. In this process, any readily volatile organic C compounds may also be transferred to the gas phase and evade detection in the liquid phase; they therefore have to be determined separately in the gas phase. The novel method makes it possible to determine the content of C compounds completely and independently of the volatility of the organic C compounds. 2.2 The water to be examined is acidified in an outgassing vessel; a carrier gas stream is passed through the water in the outgassing vessel. Water and carrier gas are fed from the outgassing vessel to a degrading reactor. The CO2 content of the carrier gas is determined downstream of the outgassing vessel and/or downstream of the degrading reactor. The proportions of inorganic and organic C compounds are determined separately from one another and/or as a total. 2.3 Determination of the content of C compounds in water down to the ppb range.
